Abstract: An automatic banding packing machine is provided with a packing machine body having an upper-face table on which the object to be packed passes, a pair of vertical band guide arches arranged separately from each other above the upper-face table in a direction parallel with a passage direction of the object to be packed, and a horizontal band guide arch arranged above the upper-face table in the direction parallel with the passage direction of the object to be packed, and the pair of vertical band guide arches is configured to be movable between a standby position separated from the horizontal band guide arch and a communication position communicating with the horizontal band guide arch in a direction orthogonal to the passage direction of the object to be packed.

Abstract: A banding packing machine capable of inexpensively detecting the end of a band reel, thereby contributing to a reduction in cost. In a banding packing machine having a back pool box in a packing machine body and serving to feed an unused band (B) stored in the back pool box and a band from a band reel, the rotating speed of a touch roller is detected when a required amount of band is being pulled out of the band reel wherein the band is not left in the band reel if the rotating speed is not changed but the rotation is carried out at an almost constant speed, and the tip portion of the band does not arrive at the predetermined position of a band guide arch. Then, the driving operation of a normal rotating roller is stopped based on the decision signal.

Abstract: It is an object to provide an automatic banding packing machine capable of easily removing the ring of a band with a simple structure when idle banding is carried out. When the rear end side of a band is to be pulled back by band pull-back means (84), an amount of the pull-back is detected by detecting means. It is decided that idle banding of the band is carried out when a result of the detection is greater than a preset length and the band is wound around a slide table. Thereafter, the rotation of a cam shaft (41) is temporarily stopped based on a signal, whereby the timing of the pressing to be carried out by a middle presser member, which is operated after melting the superposing portion of the band by means of a heater (36), is delayed in a predetermined time.

Abstract: A band refeeding method in a banding packing machine is disclosed which can prevent the tip portion of a band from being excessively pulled back even if the band is not supplied correctly but is automatically pulled back, and can stay the band in a predetermined position and can successively supply the band to the band guide arch side. A length of a band to be pulled back to an original position by band pull back means is previously detected based on the number of rotations of a touch roller constituting band supply means. In addition, the number of rotations of the touch roller before reaching a predetected set value is detected when the tip portion of the band is pulled back. Then, a rotating speed of a roller of the band pull back means is reduced when the number of rotations is detected. Therefore, the roller of the band pull back means is subsequently rotated at the low speed, thereby pulling back the tip of the band to a predetermined position.

Abstract: The distal end of a band remains held after a band-holding step. A band-tightening step is performed by operating a manual tightening switch, thereby driving a drive motor and hence rotating a drive roller under manual control. A band-sealing step and a band-feeding step are automatically and sequentially performed after a tightening stop switch is operated, generating a manual-tightening end signal. It is desirable to use a mode-changing switch for switching an operating mode of the apparatus between an automatic mode and a manual mode. The manual tightening switch and the tightening step are effective in the manual mode and are ineffective in the automatic mode.

Abstract: A controller in a banding packing machine which can easily correct a shift from the predetermined timing cycle. The controller includes a cam shaft having a plurality of cams, a timing plate which includes a plurality of holes corresponding to rotation positions of the cam shaft, and a detecting means. An inching mode is also disclosed which provides for the manual adjustment of presser members following a step in the rotation of the cam shaft.

Abstract: A brake structure of a band reel in a packing machine in which reliable braking effects can be obtained and responsiveness can be enhanced. A brake arm (15) has a coil spring portion (16) provided on one of its ends and a band passing ring portion (18) provided on the other end is mounted on one of ends of the reel shaft (13). One of ends on the coil spring (16) side in the brake arm (13) is fastened to a fixed member such as a device frame. The diameter of the coil spring portion (16) is reduced to cause the inner peripheral surface of the coil spring portion (16) to closely engage the outer peripheral surface of the reel shaft (13), thereby stopping rotation of the reel shaft by frictional force, when the force for feeding the band is released.

Abstract: A band feed length adjusting device in a packing machine which can newly input, to a control section, a length obtained by manually leading out a band to adjust the feed length of the band and can subsequently feed the band having a correct length in the case in which the size of an object to be packed is changed to be larger.

Abstract: A touch roller can be moved between three positions. In the first position, the touch roller is pressed onto a forward driving roller. In the second position, the touch roller is pressed onto a reverse driving roller with two different forces. In the third position, the touch roller is spaced from both the forward driving roller and the reverse driving roller. When the touch roller is pushed onto the reverse driving roller with a small force, the reverse driving roller pulls back a band and wraps the band around an article to be packed. When the touch roller is pushed onto the reverse driving roller with a large force, the reverse driving roller tightens the band wrapped around an article.

Abstract: With a conventional baling machine, for tying an article resting on a pallet with a band, the article resting on the pallet is required to be placed in a frame of an arch guide. To solve this problem, the present invention provides a baling machine including a main body having a band feeding mechanism, a band bonding mechanism, and a band cutting mechanism; a vertical table (3) to be aligned with an article resting on a pallet; a band guide (7) provided to be drawn out from under the vertical table (3) in a horizontal direction; a support mechanism for supporting the band guide (7) inside the main body allowing it to slide; and wheels (17) provided to the main body, wherein the band guide (7) slides above the ground contact face of the wheels (17).

Abstract: It is an object to provide a banding packing machine capable of easily processing a right presser member, a left presser member and a middle presser member, reducing the number of parts and readily carrying out attachment with high precision. A drum portion of at least a middle presser member (24) provided in a central part in a right presser member (22), a left presser member (23) and the middle presser member (24) has a sectional shape of an almost track including a pair of circular arc portions (26a, 26d) opposed to each other and a pair of straight portions (26c, 26d) opposed to each other, and one of ends of each of drum portions (27, 28) in the right presser member (22) and the left presser member (23) which are opposed to the straight portions (26c, 26d) of the middle presser member (24) is formed rectilinearly.

Abstract: A lower part 14L of a band way 14, which is incorporated in an arch unit 12, is separated from the other parts of the band way 14. A drive (air cylinder) 35 supports the lower part 14L, allowing the same to move between a substantially horizontal initial position and an inclined position. A band 13 is released from the band way 14 when a packing operation starts. Thereafter, the lower part 14L is moved from the initial position to the inclined position and compressed air is applied to the guide surface 14a of the lower part 14L, thereby removing foreign matter from the band way 14. This sequence of removing foreign matter is performed in, for example, each cycle of packing operation.

Abstract: Front end portions of respective bands drawn out of two band reels are guided in substantially parallel relationship by means of band guide 11. When the band reel in use becomes empty, band feeding unit 30 is driven in reverse to thereby discharge a rear end portion of the band and, further, a front end portion of other band in stand-by condition is moved to a position of use by means of band changeover unit 20. An automatic band charging device can be provided which enables rapidly replacing an empty band reel with a spare band reel and which has a simple structure and realizes a reduced number of constituent parts, thereby contributing to the miniaturization of the packing machine.

Abstract: A method and apparatus for manufacturing paper cushioning members in which work paper is inserted between a pair of intermittent-cutting roller members to process multiple rows of thin bands with link portion. Waste-collecting members are provided at a discharge side of the rollers to separate the work paper from the roller members and to feed the processed work paper into a wave-forming guide. The wave-forming guide includes an upper pressing member that rotates about a hinge positioned at an end nearest to the discharge side of the rollers and a counterweight positioned at a distal end of said upper pressing member such that the upper pressing member is biased toward the interior of the wave-forming guide. The wave-forming guide is designed to forcibly compress the processed work paper into finely crumpled thin bands and to discharge the crumpled thin bands in a wavy form.
